11 claims. l

The invention refers to wall supports for awnings, with joint axles, on the side facing the wall, for the upper arms oscillating in vertical planes perpendicularly disposed .in relation to the wall of the house, said upper arms being turned from their approximately horizontal position of rest parallel to the wall of the house into a position of use approximately rectangular with relation to the wall of the house when the awning is being expanded, the articulations disposed between the lowering rod and the wall support being stretched in doing so,

With known mechanisms of this type, the link axle invariably remaining inside the protective box is adjusted at a suitable angle of inclination with a view to obtaining the inclination desired of the stretched awning and iixed in that position the wall support.

In consequence of this, in the position of nonuse of the awning the arms as well as the lowering rod will assume a correspondingly inclined position, in such a way, `that the arms with the cloth will protrude from the protective box at varying heights depending upon the position of inclination adjusted.

By reason of this, the protective box must 4be of rather high construction, and its passage opening must be made very high. This .again results in the necessity of giving a considerable height to the lowering rod serving to close the opening of the protective box. In `consequence Vof this, the closing effected will be rather deficient for the reason that the lowering rod will adapt itself in varying angular relation to the exterior of the protective box depending upon .the position of inclination adjusted. For similar reasons, the angular range within which the inclination .of the awning may be adj-usted, is also limited.

To avoid these deficiencies, the support of the joint axle for the upper arm, in accordance with the present invention, is arranged With relation to the rigid portion of the wall Support bracket in a movable manner, in such a way, that the joint axle may be moved `out of the .protective box with a view to freeing the arms for the expanding motion for stretching the awn ing in any desired position of inclination. In the posit-ion of non-use of the awning the link axle is invariably held in its unchanged, by preference vertical, position while it will change to its inclined operative position when the awning is being stretched, said position being determined by adjustable stops.

By reason of this arrangement, the link arms will eventually move out of the protective box in conjunction with the point axle invariably in the same angular position. The lowering rod will lmove out of the 4protective box always in the same, preferentially vertical position, in such a way, `that the overall height of the protective box, of its passage opening and of the lowering rod may be reduced in size, a factor considered most desirable also from an architectural point of View. Independent of the inclined position of the .awning established, the lowering rod will invariably adapt itself vertically to the exterior wall of the protective box when the awning is not in use. The overall height of the passage opening and of the lowering rod is considerably reduced, furthermore, by the fact that the forked member supporting the joint axle is provided with a deep recess below the joint axle on the side facing forward when the awning is in its position of rest, with which it may come out beyond a forward closing strip of the protective box when being swung forward into its operative position, in such a way, that with a minimum height .of the projective box opening a pivoting range of the joint axle over a large angle, i. e. from 0 to 90, will be obtained.

Additional features of the invention will become evident from the claims in conjunction with the following description.

In the drawings, an embodiment of the invention is presented by way of example,

Fig. 1 being a lateral view of the wall support;

Fig. 2 isa partial front view thereof, and

Fig. 3 is a section along line III- III of lFig. 2.

The wall support bracket l is bolted to a girder 3 on the wall of the house by means of screw bolts 2, and at iron members 5 are screwed into laterally and horizontally disposed grooves 4, said iron members supporting `at their free forward ends a horizontally disposed supporting bolt 6, with a forked member l mounted thereon for pivotal motion. This forked member l serves to support in an upper fork 8 joint or link axle 9 (Fig. 3) for the articulated upper arm 'Il with which it is firmly connected by cross pin l2. This pin or joint axle is supported at its point-ed lower end I3 in a tapered bore I4 in the lower portion of the fork member. At the upper end, a bearing l5 has been inserted for the reception of the upper radial stresses exerted vby the link axle. A piece of sheet metal It serves as an upper cover to the needle bearing and the. link axle.

From roller l'l disposed in special supporting arms above the wall support, cloth I8 is passed over a cloth guiding rod I9 having' the purpose to protect the cloth against being damaged by the protruding elements of the forked member. With its foremost edge, the cloth is fastened to the transversely arranged lowering rod 2| as shown in Fig. 1. The lowering rod is linked by means of eyes provided thereon to the outer arm Il of the link in well-known fashion not shown in the drawings.

Cloth guiding rod i9 extends over the full width of the cloth; it is of rounded section and inserted in corresponding recesses 22 of all the forked members 1 of the awning, and fixed therein.

The lower end 23 (Fig. 2) of forked member 1 resting upon supporting bolt 6 is fork-shaped as well. The two fork-arms enclose an aperture 24 of the fork within which the bolt 6 supports a cam stop 25, likewise fixed to forked member 1, in such a way, that stop 25 is connected with forked member 1 to form a unit in that way joining in the oscillating movement of the latter.

Supporting bolt is provided with a number of regularly disposed longitudinal ribs engaging corresponding grooves in the holes of the cam stop and fork-arms making it possible to change the adjustment of stop at certain angular intervals in relation to forked member 1. With eighteen longitudinal ribs 2n available, the relative adjustment of stop 25 and forked member 1 will amount to 20 each. Stop 25 is in ccoperative relation with a counter-stop 26 and limits the position of inclination of link axle 9 in its swung-out operative position.

Alongside of the rough adjustment of the position of inclination between zero and 20 degrees by bolt 6, a fine adjustment has been provided which is obtained by the adjustability cf counterstop 26; for that purpose, counter-stop 26 is disposed in sliding fashion longitudinally adjustable on wall bracket. By an adjusting screw 21 it may be adjusted in any desired intermediate position within the range of rough adjustment of 20 degrees.

For the purpose of adjustment, adjusting screw 21 is equipped with a fixed collar 28. With its rearward end, the screw is pivotably supported in a vertical wall 29 of wall bracket l and secured by Cotter pin and washer 3|, 32. Adjusting screw 21 is screwed into the body of stop 26, in such a way, that by turning the collar 28 xed on the screw, stop 26 is moved forward or backward. By a lock nut 33 mounted on the adjusting screw, the position adjusted is secured.

Forked member 1 is provided with a deep recess 34 on the side facing forward when the equipment is not in use which passes into operative position when forked member 1 is swung across a covering strip 35 of protective box 36.

As may be seen from Figs. 1 and 3, link axle 8 with its upper and lower arms and the cloth as well as part of the lowering rod 2| may be swung without being hampered into an inclined position between 0 and 90, notwithstanding the reduced height of passage opening 31 in protective box 36.

The lowering rod 2| will always amply rest against the front of the protective box with its lower part 33, as may be seen from Fig. 1. In the upper part, the protective box extends beyond a forward extending part of the lowering rod 2| by way of its protruding ledge 39, in such a way, that this rod with all other moving parts of the awning will be protected against influences of the weather. On the upper side of the lowering rod a slot open to the air has been provided for ventilation.

tective box having a front opening and enclosing the awning in its position of inaction, a support for said link pin, means for moving said support with relation to the wall, the link pin being movable to said front opening by movement of said support in one direction for freeing the arm for extending motion, when the awning is being expanded, and means for adjusting the link pin to different inclination positions in a plane perpendicular to the wall in order to expand the awning in a corresponding position of inclination.
